Knuckle Cracking

Well I used to crack my knuckles alot when i was younger, and because of this my knuckles are huge and swollen. Will this interfere with my bass playing at all? I'm kind of worried about that. By the way, I play with my fingers most of the time.

This is a very generalized statement, but it is common that someone with rheumatoid factor in their blood will get the problem with popping their knuckles, but those without it can pop away. See your doc and he can order some arthritis blood tests for you. Also, consider your heritage, as rheumatoid arthritis is usually in the family somewhere.

Hmmm...so...if my grandmother on my dad's side has arthritis in her fingers, but neither of my parents, or any of my other relatives have it...then...what're my chances?
Considering the fact that I crack my knuckles a LOT, and also tend to crack my back and neck when they get too stiff, like sitting a 2 hour exam or something...

Well if you want to get into a conversation on genetics..... if your grandmother had it and niether of your parents had it, then mendalian genetics tells us that a gene is able to skip a generation of 'hide' itself. You can get into all that monohybrid crossing stuff,but it's hard to do on a computer. Sorry, just learned that in Biology, and had to share it. Then again, that's just me.

im no dr,,and guilty of being a knuckle cracker too...ive heard that doing this can lead to arthritis over time. and the more you crack the worse it gets, i heard that it leaves calcium deposits in the joint and affects finger mobility in the long run. I'll ask my Dr next time i see her
